Work on the new roundabout at US-56/77/K-150 in Marion County will begin between June 24 and June 26.
A short detour goes into effect today to accommodate the construction.
Those wanting to go west on US-56 from the US-56/US-77 intersection will go south on US-77 to K-256, then west through Marion. They will continue north on K-256 to the junction with US-56.
Those wanting to go east will use the same detour in reverse.
The detour shall be in effect until Aug. 21, weather permitting.
Plans call for the project to be completed by mid-December.
